FIRE-EXTINQGUISHER.

SPECIFICATION forming part of Letters Patent No. 286,502, dated October9, 188?.

Application filed May 2, 1883. (Yo model.)

To all whom/it may concern: I

Be it-known that I, PIERRE (Ensures EU- GENE Tanouiir, of the city ofParis, France, have invented Improveinenicnts in Fire-EX- tinguishers,of which the following is a full,

clear, and exact description.

The objectof my invention-is to produce an improved fire-extinguishingapparatus pre" senting all the required conditions of security andconvenience of working. This apparatus is arranged in such a manner asnot to be charged and putunder pressure except at the moment that it isrequired for use, and this can be effected in the space of a few secondsand I 5 without requiring any special. knowledge.

In order that my invention may he better understood, I have representeddifferent views in the annexed drawings of an extinguisher arrangedaccording to my invention, but as a specimen only. I

Figure 1 shows a vertical section of the extinguisher not as yet underpressure. Fig. 2 represents a similar section of the apparatus underpressure. Fig. 3 represent-s a section through the center of theclosing-crown of the apparatus. Fig. 4 is a plan view of the cover andclosing-crown. Fig. 5 represents in vertical section a detail, on anenlarged scale, of the safety-valve. Fig. 6 is a sectional elevation ofthe cap and its gallery, showing a modification of the hook on the endof the screw. Fig. 7 also represent 3 a variation in the manner ofclosing the bottle. F1 Sis a vertical section of the upper part of thevessel with the movable crown -re1noved. Fig. 9is a vertical section ofthe safety-valve, taken on a line at right angles to that on which Fig.5 is taken.

ais the body of the apparatus, provided with handles 12, and having thewater-supply tap c,

upon which a hose terminating in a nozzle is to be secured. Thisrecipient a, which is by preference cylindrical. in shape, but of whichthe form mayyary, has at its upper part a fixed crown, (2, upon theupper surface of which is placed awasher, e, of india-ruhber, leather,or other elastic matter. Up on this fixed crown turns a second crown, f,Figs. 3 and 4, furnished with handles or ears the rim h of this crownhaving three notches, i, and three inclined planes or cams, 7c.

The cap Z, which closes the apparatus, has

three lugs, Z projecting from its riin Z, which bears upon theindia-rubber ring of the fixed crown (Z. This cap is placed in such aman nor that its lugs enter the threenotches i of 5 5 the movablecrownf, and in turning this crown having a washer. n, furnished withindia-rubher at its lower part, and a hook, at, of which the end iscurved horizontally, so as to per unit a rod, 0, to be easily hooked toit, and of which the use will be hereinafter explained. In place of thehook on the lower end of the screw, the silnie may be provided with aslot, 91, as shown in Fig. (i.

The cap 7 has a gallery, p, depending from its under surface, and itcarries the safetyvalve q, formed of a little elastic block, 1', ofindia-rubber, for example, surmounted by a cupel, s", and provided witha metallic pin, 8, Fig. 5, projecting into the cupel, and serving toguide it into the cap q, which cap is pro vided with eduction-ports sand screws upon the seat 1- of the valve. curedin the cap q in anysuitable manner. By turning more or less the cap q, the indie.- rubberis proportionately compressed, and the pressure is thus regulated atwhich the valve opens. 8 The rod 0, of which we have above spoken,carries two stoppers, t and n, of which the second is larger than thefirst, and is sustained by a metal washer, r, fixed upon the rod 0 inany convenient manner-as, for example, by 0 means of a thumb-screw, w.The stopper t is rigidly secured to the upper end of the rod 0, and thestopper n is fitted loosely thereon. The stoppers i and a, which areproperly tarred over, support a bottle, on, open at both 9 5 ends, andof any convenient form and material, upon which they are sealed withscalingwax.

Thus arranged the working of the apparatus is as follows: It is suppliedwith water in which 100 has previously been dissolved a proper quantityof alkaline powder, by preference having The cupel s is sefor its base abicarbonate of soda. The levelof the alkaline solution in the apparatusis an indefinite period of time, for there exists. no interior pressure.

When it is wished to charge the apparatus, the cap I is raised and arod, 0, is hung to the hook n or to the slot, carrying a bottle, at,sealed, and containing a preparation which will disengage carbonic acid,for example, or any sort of acid. This done, the cap is replaced uponthe apparatus, which has then the appearance represented in Fig. 1. Uponturning the handle z of the screw m in the proper direction this screwis raised, and with it the rod 0 and bottle The upper edge of thislatter comes in contact and abuts against the gallery 1), and bycontinuing to turn the screw the two stoppers t and a are dragged outand the bottle falls, as indicated in Fig. 2, discharging its contentsinto the alkaline solution in the apparatus. From this results thedisengagement of gas, establishing the pressure in the apparatus. Thebottle at a is supported by the lower stopper, u, and the pressurewithin the apparatus acting upon the washer n, furnished withindiarubber, forces the same tightly against the cap and hermeticallycloses the apparatus automatically, and prevents any leaking of the gasor liquid.

Although the pressure in this apparatus becomes very great, (aboutfourteen atmospheres,) its working does not present any danger onaccount of the safety-valve above mentioned.

InFig. 7, A is the central suspending-rod of the bottle E, carrying thecutting-washers D. These washers are drawn by the rod A y when it iswished to charge the apparatus, and

tightening-nut screwing upon the lower end of the screwed rod A.

I claim- 1. In a fire-extinguishing apparatus, the combination, with thevessel a, provided with the fixed crown d, having the elastic ring 6 onits upper surface, of the movable crown f, provided with the handles 9,the rims h, having notches z and the inclined planes or cams k, and thecap Z, having lugs projecting from its rim, substantially as hereinshown and described.

2. In a fire extinguishing apparatus, the combination, with a vessel, ofa bottle open at both ends and provided with stoppers, and suspendedfrom the cap of the said Vessel, and means, substantially as hereinshown and described, for removing the stoppers of the bottlesimultaneously, as set forth.

3. In a fire extinguishing apparatus, the combination, with avessel andits cap provided with a gallery, of a screw passing through the cap, arod secured to the lower end of the screw and carrying a loose and arigid stopper, and a bottle open at both ends, substantially as hereinshown and described.-

4. In a fire extinguishing apparatus, the combination, with the vessela, the cap Z, provided with the gallery 12, and means'for securing thecap to the vessel, of the rod m, provided with the washer a and the hookn, the rod 0, the stoppers t a, the former rigidly secured to the rodand the latter fitted to slide thereon, and the bottle 00, substantiallyas herein shown and described.

5. In a fire extinguishing apparatus, the safety-valve q, consisting ofthe seat 1-,the cap q, having eduction-ports s, and the elastic block1-, provided with the pinsand the cupel 8 sub stantially as herein shownand described.
